Mizuki Nanami - Seira and Tetsuya's childhood best friend. All three when together are very mischievous, often causing trouble throughout the school.

Hikami Sayaka - Seira's teammate. They often butt heads with each other due to their clashing personalities. However, they grudgingly begin to respect each other and slowly become friends.

Transformation Sequence

Cure Fantasia

Seira holds up her Heart Mirror with her ring glowing a bright purple. She then swipes the ring across the mirror shouting "Pretty Cure, Medley Start!". Music staffs wrap around her legs and body before flashing in a shower of purple light revealing her heels and outfit. She raises her arms above her head with musical staffs surrounding them with her gloves appearing in a flash of purple light. Her hair then fades from indigo to lavender before then getting put into a ponytail with purple bow, she then tilts her head to the side as purple earrings appear.  She then flies down from the sky and introduces herself.


Fantasia Eclipse - Cure Fantasia summons her Melody Mic before twirling it around summoning light purple orbs of moonlight. Then she shouts the attack name into the Mic and pointing it at the enemy. The orbs then gather into a giant sphere before being fired at the enemy in a beam.

Fantasia Reflection - Cure Fantasia summons her Melody Mic before twirling it around and pointing it at the enemy summoning five mirrors surround the target. All of them soon began glowing before firing 5 beams of light at the enemy.
